Clause 49 Comments

Title: Clause 49 Comments

In clause 49, the scrambler polynomial shown on p. 167 line 19 does not appear to match the serial reference implementation shown Figure 49-6 on the same page.  The taps out of the shift register for the specified polynomial should be after S38 and S57 (counting from S0) rather than S39 and S57.  The same problem exists in the descrambler presentation on the next page. 

The polynomial matches the proposal (after relabeling as noted in the editor's note on p. 167), so the figures seem to be at fault.
